Fish is also good for your eyes!
You already know that fatty fish, like salmon, is good for your heart. Well, the latest research shows it may also be good for your eyes.
"There's some evidence, it's observational, but a large study, that suggests people who have diets rich in fish, fish that is rich in omega-3 fats, have a lower instance of macular degeneration,” said Dr. John Swartzberg, head of the editorial board of the UC Berkeley Wellness Letter. “And that's great because macular degeneration is the most common cause of blindness in the elderly in the United States."
Eating fatty fish – like salmon, mackerel, freshwater trout, herring, sardines and albacore tuna – may reduce the risk of diabetic retinopathy, a complication of diabetes that often causes blindness.
In a study reported in JAMA Ophthalmology in 2016, researchers followed 3,400 seniors with type 2 diabetes. Those who ate an average of at least 500 milligrams of marine omega-fats a day – that's equal to about 2-3 servings of fatty fish a week – were half as likely to develop retinopathy as compared to those who ate less.
"If you can prevent that, you can prevent blindness in people with diabetes because blindness and diabetes do together,” Swartzberg said.
